the volume of a sphere. The difference between the high-and low-level binding is that
the high level uses methods such as
multiply()
and
subtract()
instead of the
operators
*
and
-
. When using low-level binding, you use a derived
NumberBind-
ing
class such as a
DoubleBinding
class. With a
DoubleBinding
class you
override its
computeValue()
method so that you can use the familiar operators
such as
*
and
-
to formulate complex math equations:
